Infinite interrupt loop with DataChute (i82365)

I've been working on cloning about 50 machines (surplus AST P-133's) with the Antec DataChute PCMCIA ("Via" i82365 compat. chips) controllers. All of the machines are identical (from BIOS settings and versions to hard drive images). I am working with CompactFlash PCMCIA devices.

On about 10% of the machines, I repeatedly get a nasty message on console when I insert a card: "i82365: infinite loop in interrupt controller". It's appeared (rarely) on some of the other machines, but consistently on that 10%.

I'm running kernel 2.2.14 and pcmcia-cs 3.1.14. I've played with the "cs_irq" and the "irq_list" options (I have more than 3 available IRQ's on the machine), to no avail.

As these machines will be unattended, stability is extremely important. :)

If anyone has experienced this before, or has any ideas on what to do, I would really appreciate it!
